Unique padding specifically designed for Running

The Design of Thorlos Padded Running Socks

Insights into the design, development and testing of Thorlos activity-specific, clinically-tested padded running socks from David Varsik, THORLO's senior design engineer.

What Independent Clinical Studies Say About Thorlos

Thorlos padding has been the subject of eight independent clinical research studies that were published in peer-reviewed medical journals. The results showed the proprietary padding reduces foot pain, blisters and other foot conditions, pressures on the foot and moisture.


  • Constructed with THOR•LON® fibers for superior softness, resilience, durability, and moisture-wicking for drier, better feeling feet.
  • Cushioning over the toes to help protect against runner’s toe.
  • Flat knit instep and cushioning in arch for better fit, more support and less pressure on the feet for a more comfortable run.
  • Low profile toe seam won’t rub or irritate the feet.
  • Unique padding specifically engineered for running, clinically shown to reduce blisters, pain, pressures and moisture for maximum protection.

    Best socks for running

    Different from original.


    Maybe it's my imagination, but the socks I that are being made now seem thinner than those I use to purchase and don't seem to last as long, showing wear on the soles and heels rather quickly. I have purchased Thorlos for years as a runner and loved them. These are still the best I can find, but I am wondering if there was a change in the yarns they are now using.

    Excellent socks for running support


    They are very comfortable and provide me with the exact support advertised. I would recommend these socks to anyone, and am certain they would be satisfied.

    Best work socks ever!!!!!!


    I am a 69 y/o hospital floor 12 hour shift working RN. Believe me when I say I haven't worn ANY socks other than Thorlos since I found them in 1992. They are the best. On occasion couldn't find them in the stores. And so was reduced to repairing the few remaining pairs of socks I had to keep my feet moving.

    Comfy Socks


    These socks make your feet feel pampered. I wore them up Stone Mountain and back down and my feet felt great. They wick moisture and they are soft and the padding is very shock absorbent. I will be ordering more. I think I will try the mini-cuff ones next.

    Still the best running sock for me


    I have used this type of sock for last ten years. Percent purchased pair was just as comfortable and of better quality than previous. Good to see the committment to quality manufacturing. Highly recommended

    Would wear if I was a runner


    They are very comfortable. However I will still stick to my hiking socks for work and recreation. They are heavier and more padded. Love my Thorlos. Haven't worn anything else since I discovered them years ago at a rodeo. Was introduce to them by a cowboy boot vendor when my new boots were hurting my feet. Never looked back!

    Toe tore out after second run


    After my second run the toe tore out. $16 for two runs. No thanks.

    Best Socks for Walking


    I love the thickness of the sock on the front, toe and heel areas. It's like walking on a thick carpet
